Features of ONEILL Heat 5mm Round-Toe Booties 4789-002

• FluidFlex Neoprene Construction (5mm): Premium neoprene material designed for superior flexibility and thermal retention in cold water
• Round-Toe Design: Specifically shaped to maximize warmth by reducing water circulation around the toes
• Anti-Flush Ankle/Secure Shin Strap: A secure closure system (strap or seal) designed to minimize water flush entering the boot
• Easy-Entry Heel Pull Tab: Integrated pull tab on the heel for effortless on and off, even with wet hands
• Torsion Control Forefoot: Strategic flex zones in the sole that allow for natural foot bending and board feel while maintaining insulation
• Durable Textured Rubber Sole: High-traction, abrasion-resistant sole for grip on slippery rocks, reefs, and surfboard decks
• Fully Taped, Glued & Blindstitched Seams: Seam construction that reinforces critical stress points, significantly reducing water ingress and increasing durability
• Anatomically Pre-Shaped Fit: Boots are designed to match the natural contours of the foot for reduced fatigue and chafing
• Integrated Drainage/Ventilation Channels: Small internal channels that allow for water to escape and air to circulate, preventing a "soggy" feeling
• Reinforced High-Wear Zones: Additional material or rubber protection in areas prone to abrasion, such as the toe cap and medial side, for extended product life

Product Info for ONEILL Heat 5mm Round-Toe Booties 4789-002

Designed to be the final piece of your thermal armor, the O'Neill Men's Heat 5mm RT Booties deliver head-to-toe protection born from the brand's legacy in extreme conditions. The premium 5mm FluidFlex neoprene offers a perfect balance of cold-water warmth and exceptional flexibility, allowing for natural foot movement and all-day comfort in temperatures from 60°F/15.5°C and below.

An anatomical fit combined with the signature round-toe design maximizes heat retention, while the critical anti-flush shin strap locks out water to keep your core temperature stable. For agile, high-performance surfing, the torsion control forefoot enhances board feel and power through turns. Durability is uncompromising, with fully taped, glued, and blindstitched (GBS) seam construction - a technology that seals needle holes to drastically reduce flushing and heat loss. This is paired with a heavy-duty, textured rubber sole for confident traction on slippery rocks and reefs, and an easy-entry heel pull tab for quick suiting up.

To ensure maximum warmth and performance, correct sizing is key. O'Neill uses a lettered system; a common tip from seasoned users is to size down if you are between sizes for a snugger, more secure fit. Whether you're surfing, paddling, or kayaking, the Heat Booties provide the reliable, integrated protection you need to excel when the conditions are at their most demanding.
